Struct boing::color::Picker

pub struct Picker<'ui> { /* private fields */ }

A button that opens a color picker dialog.

Implementations

impl<'ui> Picker<'ui>

pub fn selected_color(&self) -> Color

The color currently selected by this picker.

pub fn select_color(&self, color: Color)

Selects the given color.

Panics

Panics if any components of color are not normalized to the [0.0, 1.0] range. See [select_color_unchecked] for an unchecked version of this function.

pub unsafe fn select_color_unchecked(&self, color: Color)

Selects the given color without first checking if it is valid.

Safety

All components of color must be normalized to the [0.0, 1.0] range.

pub fn on_selected<F>(&'ui self, f: F)where F: 'ui + FnMut(),

Sets a callback for when the user selects a new color.

This callback is unset by default. This is not activated when select_color or select_color_unchecked is called.

Methods from Deref<Target = Control>

pub fn is_visible(&self) -> bool

Determines if this control is visible.

Controls are visible by default except for Windows, which are invisible by default.

pub fn is_enabled(&self) -> bool

Determines if this control responds to user interaction.

Controls are enabled by default.

pub fn is_enabled_to_user(&self) -> bool

Determines if this control, and all of its parent controls, are enabled.

If this control is not a child of a parent control, then this function is equivalent to is_enabled.

pub fn native_handle(&self) -> *mut c_void

A handle to the underlying OS object.

pub fn show(&self)

Makes this control visible.

pub fn hide(&self)

Makes this control not visible.

pub fn enable(&self)

Makes this control enabled.

pub fn disable(&self)

Makes this control not enabled.
